'''HP-19B''', introduced on 4 January 1988, along with the [[HP-17B]], [[HP-27S]] and the [[HP-28S]], and replaced by the '''HP-19BII''' (F1639A) in January 1990,<ref>{{cite web |url=http://www.vcalc.net/hp-date.htm |title=HP Calculators by Date of Introduction |date=2003-01-22}}</ref> was a simplified [[Hewlett Packard]] business model [[calculator]], like the 17B. It had a clamshell design, like the [[HP-18C]], [[HP-28C]] and 28S.<ref>{{cite web |url=http://hp.giesselink.com/emu42.htm |title=HP Page of Christoph Giesselink |access-date=2010-12-28 |date=2010-08-31}}</ref>
Two common issues with the clamshell case were the plastic surrounding the battery door would break under pressure from the batteries; and the ribbon connecting the two keyboards would begin to fail after numerous case openings.
The calculator included functions for solving financial calculations like time value of money, amortizing, interest rate conversion and cash flow.  Business functionalities included percentage change, markup, currency exchange and unit conversions. It also had math capabilities such as trigonometry and graphing. Upscale functionality, at the time of release, included the ability to design your own problem solving equations and storing text directly in the calculator using the letter keyboard on the left side. The calculator could also print via a built-in infrared transmitter to a supported infrared printer such as the HP 82240A or HP 82240B; which allowed you to print out the generated graphs.
<!-- There were two versions, the US one working in English only, and the international one with a choice of six languages. Code name: Trader. It was a 132×16 [[Dot matrix display|LCD dot matrix]], 22×2 characters simplified business calculator, like the HP 19B.<ref>http://www.thimet.de/calccollection/Calculators/HP-17BII/Contents.htm {{Dead link|date=February 2022}}</ref>
Used a [[Saturn (microprocessor)|Saturn processor]] and had a memory of 8000 bytes, 6750 bytes available to the user. Was code named ''Trader'', and belong to the 17B family (HP-17B, [[HP-17BII]], [[HP-17BII+]]) and the Pioneer series.<ref>http://www.fbalzer.de/tr/pioneer.html {{Dead link|date=February 2022}}</ref> -->
